rpmdep.pl

NAME

rpmdep - display the full dependency of an installed rpm package

DESCRIPTION

rpmdep is an improved 'rpm -qR' command : it search recursively for package dependencies, and resolvs all dependencies to package names. It can also prepare a file to build a graph of dependencies, with graphviz.

SYNOPSIS

rpmdep.pl [options] package

options:

   -help                brief help message
   -man                 full documentation
   -V, --version        print version
   -use-cache           use cache file instead rpm query
   -clear-cache         clear cache file

   -verbose             verbose
   -dot dotfile         build a dot file for graphviz
   -depending           instead of dependencies, display dependings
   -all                 works on all installed packages

REQUIRED ARGUMENTS

a package to analyse. Only one name may be given. It is not necessary if you are using the -all option.

OPTIONS

-help

Print a brief help message and exits.

-man

Print the manual page and exits.

-version

Print the program release and exit.

-verbose

The program works and print debugging messages.

-dot

create a dot file to be used by graphviz. in normal call, an arrow from a to b means that a package depends (uses) b package. in dependings call, an arrow from a to b means that a package is used by b package.

-use-cache

the rpm query may be long (10 to 30 s). If you will run an rpmorphan tool several time, this option will allow to gain a lot of time : it save the rpm query on a file cache (first call), then use this cache instead quering rpm (others calls).

-clear-cache

to remove cache file. Can be used with -use-cache to write a new cache.

--depending

instead of showing package dependencies (rpm -qR), display packages wich are depending upon the given argument : it then act as an improved 'rpm -q --whatrequires' command

--all

rpmdep will then work on all installed packages, and display the results sorted by the number of depends (or dependings).

USAGE

get the full list of dependencies for rpmrebuild package

  rpmdep.pl rpmrebuild

get the full list of dependencies for rpmrestore package and build the graph data file (rpmrestore.dot)

  rpmdep.pl -dot rpmrestore.dot rpmrestore

build a png graph image from the graph data

  dot -Tpng rpmrestore.dot -o rpmrestore.png

get depending package of perl

  rpmdep.pl --depending perl

check is a package is an orphan

  rpmdep.pl --depending afick-gui

list all package dependencies

  rpmdep.pl -a

list all packages dependings and prepare a graph

  rpmdep.pl -a --depending --dot alldep.dot

FILES

the program can use the /tmp/rpmorphan.cache file

DIAGNOSTICS

the verbose mode allow to see all the recursive work

others messages are

package ... is not installed

this is not a name of an installed package

... has no dependencies

this can comes for some admin tools (ash for example)

... depends upon (list)

return a list of sorted and comma separated packages

... is needed by (list)

return the depending package list

no depending : ... is an orphan

the given package has no depending packages : it is an orphan

EXIT STATUS

O if all is ok

>=1 if a problem

CONFIGURATION

nothing

DEPENDENCIES

you should use graphviz to build graph from

INCOMPATIBILITIES

not known

BUGS AND LIMITATIONS

the program does not work well on program installed in several versions

NOTES

this program can be used as "normal" user
